The settlement between King George and Nicholas I was signed on 16 August 1460: the King finally accepted the rule of the Duke of Opole over Strzelce, Niemodlin and Olesno, but in exchange Nicholas I had to resign his claims over the Duchy of Opawa (he bought the Duchy in 1454 from his co-ruler Ernest, but as a result of the King's strong opposition, Nicholas I wasn't able to take effective control over this land).
